2 Application filed Jul 13,

To all whom it may concern:

Be it known that I, Ormnnnv H. N nnsni, a citizen of the United States,and a resident of Norman Township, in the county of Grundy and State ofTllinois,have invented certain new and useful Improvements in RoadGraders, of which the following is a specification. I

This invention relates to improvements in road graders and moreparticularly to the means for collecting and distributing the dirt.

An important object of this invention is to provide a road graderwherein the main blade of the same is provided at its ends with hingedwings or extension blades which are positioned for the purpose ofpicking up a quantity of dirt for filling the low places in the road andfor leveling roads.

A. further object is to provide a road grader having its blade providedwith wings which may be readily and conveniently adjusted as theoccasion requires for varying the quantity of dirt moved by the blade.

A further object of the invention is to provide a road grader bladewhich is of simplified construction, simple to operate and cheap tomanufacture.

Other objects and advantages of the in vention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this application, andwherein like numerals are employed to designate like parts throughoutthe same,

Figure l is a fragmentary perspective of a road grader constructed inaccordance with this invention, the View illustrating a portion of thescraping blade and one of the wings,

Figure 2 is a plan View of the improved wing, the attaching plate of thesame being shown in section, and

Figures 3, 4t and 5 are plan views of the blade and wings of the same,the views illustrating the various positions assumed by the wings.

In the drawings, wherein for the purpose of illustration is shown apreferred embodiment of the invention, the numeral 5 generallydesignates a grader which is provided with an adjustable blade 6 capableof as suming any of the positions illustrated in Figures 3, 4 and 5. Thegrader maybe of standard construction and the means for adjusting theblade 6 may be of any desired Specification of Letters Patent. PatentdAug, 8, 1922 1921. Serial no. 484,363.

' type. The grader may be propelled by any suitable means and it iswheels 7 The invention forming the subject matter of this application isin the nature of wings arranged at the ends of the blade so that as theblade moves forwardly a quantity of dirt will be picked up to beemployed for filling holes in the direction of travel. Also, whengrading roads, the wings may be employed to pick up the dirt at the topof a hill and subsequently deposit the dirt at the bottom of the hill,thereby leveling the road.

Specifically, a wing 10 is arranged at each end of the blade and isprovided with a triangular terminal portion 11 bent upon the body of thewing and secured thereto by rivets or other fastening devices 12. By

mounted upon bending the terminal portion 11 upon the body of the Wing10, a hinge barrel 12 is formed, which hinge barrel receives a hinge pindesignated by the numeral 18. The hinge pin 13 is passed through a pairof alined hinge'barrels 15 formed at one end of an attaching plate 16.The attaching plate 16 is secured to the rear side of the blade by meansof rivets 0r suitable fastening devices 17 and has its contact surfaceslightly concaved, as illustrated in Figure 3. It is thus seen that apair of the wings lOma be readily and conveniently attached to a b adeof a standard grader without altering the construction" of the grader orwithout excessive effort on the part of the operator. The hingebarrels15 have their outer sides rounded and are engaged by the rear ends ofthe wings 10 so as to brace the wings as the same engage the dirt duringtravel. The lower longitudinal edge of each blade is inclined. upwardlyas indicated at 18 so that when the same engages hard projections intheroad, the wings will be elevated and will thereby ride over theprojectio'n. Also, the upper edge of the wing 10 may be beveled at itsforward end as indicated at 20, so that the excess dirt picked up by thewings and blade will ride over the top of the wings. It is understood ofcourse, that the wings may be made of any desired strength or thicknesswithout departing from the spirit ofthe invention.

The wings 10 may be separately and independently adjusted with relationto the blades by means of chains 22 secured to the forward ends of thewings by hooks 24 and connected to a suitable part 25 of the grader,

as indicated at 26. The attaching member 26 may be in the nature of ahook and is engaged by one of the links of each chain. It is thus seenthat the wings 10 may be adjusted angularly with relation to the blade,by engaging the proper link of the chain 22 with the hook 26.

In operation, the wings may be positioned as illustrated in Figure 3, inwhich case one of the wings is shown in its inoperative position whilethe other is shown as being directed forwardly so as to cooperate withthe blade in collectinga quantity of dirt for subsequent deposit in alow place in the road.

Or, if desired, the blade and the wings may be positioned as illustratedin Figure 4, wherein the blade is shownarranged at an angle to the pathof travel of the ma chine with one of the wings extended forwardly andthe other extended rearwardly. ll hen the blade and the wings are thuspositioned, a quantity oi dirt is collected by one 01 the wings and theblade for removal to a point in the road to be filled.

Further, both oi the wings may be extended forwardly as illustrated inFigure 5, in which case, dirt is collected by both of the wings and theblade. In this case, the grader is operated for leveling the road andthe dirt is collected at the top of a hill and deposited at the bottomof the hill, in the usual manner.

With reference to the foregoing description, taken in connection withthe accompanying drawing, it will be apparent that a road graderattachment constructed in ac cordance with this invention willei'iectlvely cooperate with the scraping blade in collecting the dirtand subsequently depositing the same in a low place in the road.

I claim 1. An attachment for road graders comprising an attaching plateadapted to be secured to the scraping blade oi? the grader and having apair of alined hinge barrels, a wing having a triangular portion bentupon itselt and secured to the wing, whereby to form a hinge barrelalined with said first and second named hinge barrels, and a hinge pinpassed through said first and second named hinge barrels.

2. An attachment for road graders COD1- prising an attaching plateadapted to be secured to the scraping blade of the grader and having apair of alined hinge barrels, a wing having a triangular portion bentupon itself and secured to the wing, whereby to form a hinge barrelalined with said. first and second named hinge barrels, a hinge pinpassed through said first and second named hinge barrels, and meanswhere by said wing may be adjusted with relation to the blade to whichit is attached.

3. An attachment for road graders comprisingan attaching plate adaptedto be secured to the scraping blade of: the grader and having a pair ofalined hinge barrels, a wing having a triangular portion bent uponitself and secured to the wing, whereby to form a hinge barrel alinedwith said first and second named hinge barrels, a hinge pin passedthrough said first and sec- 0nd named hinge barrels, and means wherebysaid wing may be adjusted with relation to the blade to which it isattached, the lower edge off said wing bein beveled.
